    Default Any clue what these orange spots may be in on the joists in the crawl space?

    Any advice would be great! Thanks

    Mold.

    Paint splatters.

    You need a better camera if you want better help.

    purely a guess or two after viewing blurry out-of-focus poor image:

    WAG 1: (Possibly not-quite properly fully shaken) over-spatter from draftblocking expanding foam (can dispensing straw or nozzle) or immulescent (sp) paint. These products for specific usages are color-tinted bright orange, red, etc. depending on their approved applications.

    WAG 2: Marking spray chalk, marking paint splatter, or marking spray paint splatter (such as a builder marking TELECO or CA-TV entrance during or just before rough-in contractors arrive or for framing inspection) (orange-communications, red-electric, blue-potable water, yellow-fuel gas, green- etc.).

    Unsure if the spun insulation pictured is similarly effected, photo looks like some similarly tinted orange might be present upon same behind and above near what I can only guess is the mudsil or sill plate/sole plate intersection or a "penetration" to the adjacent wall and/or floor assembly, near, behind, above, or beyond the "floor joist".

    Solicited "any advice": Agree with JK, either get better at using the image device you have, or acquire a better one. (Unclear what "advice" you're seeking and why you need/want "advice" regarding what?).

    HTH.

    Looks like sap to me. It's fairly common for wood members.
